Dispersion Stability of 14 Manufactured Nanomaterials for Ecotoxicity Tests Using .

Int J Environ Res Public Health 2022 Jun 10;19(12). Epub 2022 Jun 10.

Department of Chemical and Molecular Engineering, Hanyang University, 55 Hanyangdaehakro, Sangrok-gu, Ansan 15588, Korea.

The development of nanotechnology has increased concerns about the exposure of ecosystems to manufactured nanomaterials, the toxicities of which are now being researched. However, when manufactured nanomaterials are mixed with algae in a culture medium for ecotoxicity tests, the results are vulnerable to distortion by an agglomeration phenomenon. Here, we describe a dispersion method commonly applicable to ecotoxicity tests for the 14 types of manufactured nanomaterials specified by the Organisation of Economic Co-operation and Development's Sponsorship Programme, namely aluminum oxide (AlO), carbon black, single-walled carbon nanotubes (SWCNTs), multi-walled carbon nanotubes (MWCNTs), cerium oxide (CeO), dendrimers, fullerene, gold (Au), iron (Fe), nanoclays, silver (Ag), silicon dioxide (SiO), titanium dioxide (TiO), and zinc oxide (ZnO).

Ferroptosis as a mechanism of non-ferrous metal toxicity.

Arch Toxicol 2022 Jun 21. Epub 2022 Jun 21.

Laboratory of Molecular Dietetics, IM Sechenov First Moscow State Medical University (Sechenov University), 119435, Moscow, Russia.

Ferroptosis is a recently discovered form of regulated cell death, implicated in multiple pathologies. Given that the toxicity elicited by some metals is linked to alterations in iron metabolism and induction of oxidative stress and lipid peroxidation, ferroptosis might be involved in such toxicity. Although direct evidence is insufficient, certain pioneering studies have demonstrated a crosstalk between metal toxicity and ferroptosis. Read More
